Gallium heat pipe for reactor and heat exchange device

Abstract

The invention discloses a gallium heat pipe for a reactor and a heat exchange device. The gallium heat pipe comprises a pipe body; one end of the pipe body is a condensation section, the other end of the pipe body is an evaporation section, and a heat insulation section is arranged between the condensation section and the evaporation section; and the gallium heat pipe is characterized in that a liquid absorbing core, gallium and related working media are arranged in the pipe body, and the interior of the pipe body is filled with gallium and the related working media, the gallium and the related working media circularly flow in the pipe body. According to the gallium heat pipe, the liquid metal gallium serves as a basic working medium, the gallium is in a liquid state at the temperature of 29.76 DEG C, and the liquid gallium has a wide temperature range and good heat stability; the gallium heat pipe can be applied to medium and low temperature systems and high temperature systems; the gallium heat pipe is wide in implementation range, simple, convenient and efficient; and the gallium heat pipe is particularly suitable for a movable small reactor and can be applied to the wide fields of comprehensive energy systems, space nuclear reactors, cooling, deep sea, military and civil integration and the like.

Description

technical field [0001] The invention belongs to the field of energy including nuclear energy and the field of mechanical equipment, and in particular relates to a high-efficiency heat transfer gallium heat pipe. Background technique [0002] Since Gaugler proposed the working principle of heat pipes, heat pipes have been developed for decades, and various types have been derived, but from the most basic point of view, heat pipes are still an efficient heat transfer element that combines boiling and condensation organically. In the past few decades of rapid development, the requirements of various working conditions have promoted the in-depth research on the principle of heat pipes and the design and development of new structures, and derived thermosiphons, reciprocating heat pipes, pulse heat Different types of heat pipes such as variable heat pipes and high temperature heat pipes. [0003] Heat pipes are classified according to temperature into low temperature heat pipes (...

Problems solved by technology

Although gallium's unique properties may have many applications, few industrial applications are currently available

[0005] In the computer field such as CPU heat dissipation is used, but no matter desktop or notebook, generally speaking, the normal operating temperature range is not higher than 85 ℃, which belongs to the category of normal temperature heat exchange, and these gallium media are mostly used in the computer field, which is non-heat pipe exchange Heat form; some liquid metal multi-media heat pipes such as mercury, zinc, and gallium are used in the range of 1800°C-2300°C. The temperature is too high, which is not suitable for the characteristics of the neutron physical and chemical environment in the reactor, and is not suitable for nuclear energy including small reactors. field

[0006] The heat transfer in nuclear reactors is complicated. The conventional heat pipes only include liquid-gas phase transition and its reverse phase transition, and the heat load is often constant. However, the working temperature range in heat pipe applications is very wide, especially It is in the complex alternating high heat flux heat load field, its working process not only includes all the phase transition processes of the above-mentioned ordinary heat pipes, but also often includes solid-liquid phase transition and its reverse phase transition, which is much more complicated than that of ordinary heat pipes. many
